Definitions

  • the present invention relates generally to blood monitoring devices and, more particularly, to a volume metering test device for obtaining a sample of blood.
  • One example of a need for quickly obtaining a sample of blood is in connection with a blood glucose monitoring system where a user must frequently use the system to monitor the user's blood glucose level.
  • Those who have irregular blood glucose concentration levels are medically required to self-monitor their blood glucose concentration level.
  • An irregular blood glucose level can be brought on by a variety of reasons including illness, such as diabetes.
  • the purpose of monitoring the blood glucose concentration level is to determine the blood glucose concentration level and then to take corrective action, based upon whether the level is too high or too low, to bring the level back within a normal range.
  • the failure to take corrective action can have serious implications.
  • hypoglycemia a condition known as hypoglycemia
  • a person can become nervous, shaky, and confused. That person's judgment may become impaired and that person may eventually pass out.
  • a person can also become very ill if their blood glucose level becomes too high, a condition known as hyperglycemia. Both conditions, hypoglycemia and hyperglycemia, are potentially life-threatening emergencies.
  • a prior art blood glucose testing device 100 is illustrated in FIG. 1 .
  • the portable nature of these devices 100 enables the users to conveniently test their blood glucose levels wherever the user may be.
  • the glucose testing device contains a test sensor 102 to harvest the blood for analysis.
  • the device 100 contains a switch 104 to activate the device 100 and a display 106 to display the blood glucose analysis results.
  • a drop of blood is obtained from the fingertip using a lancing device.
  • a prior art lancing device 120 is illustrated in FIG. 2 .
  • the lancing device 120 contains a needle lance 122 to puncture the skin. Some lancing devices implement a vacuum to facilitate drawing blood.
  • the blood is harvested using the test sensor 102.
  • the test sensor 102 which is inserted into a testing unit 100, is brought into contact with the blood drop.
  • the test sensor 102 draws the blood to the inside of the test unit 100, which then determines the concentration of glucose in the blood.
  • the results of the test are displayed on the display 106 of the test unit 100, the test sensor 102 is discarded. Each new test requires a new test sensor 102.
  • EP 0 483 117 A2 discloses a test device adapted to test a concentration of an analyte in a fluid comprising a pickup area having a first volume for receiving the fluid, and a read area in fluid communication with the pick up area and having a second volume less than the first volume, such that read area is adapted to receive fluid from the pickup area only after the pickup area is full, the read area containing a reagent adapted to produce a reaction indicative of the concentration of the analyte in the fluid.
  • test sensor used needs a minimum amount of blood to provide accurate results. If the proper amount of blood is not received, inaccurate results may be generated.
  • Another problem associated with some conventional test sensors is that the user cannot ensure that the proper amount of blood has been obtained. The user applies the blood directly onto a read area and then obtains a reading from the device. If an unusual reading is given, the user may surmise that the unusual reading was caused by an improper amount of blood being obtained. The user may then try again. There is no way for the user to know, however, if that is the true reason for the unusual result.
  • Another problem associated with some conventional test sensors is the presence of air gaps in the blood sample that is being read. Air gaps in the blood sample can also cause inaccurate readings, requiring the user to retest.
  • Another problem associated with some conventional test sensors is that the user's blood physically contacts the elements within the testing unit. Cross-contamination can be a problem if the monitoring device is used by more than one user, such as in a doctor's office or other clinical setting.
  • the invention is about a test sensor adapted to test a concentration of an analyte in a fluid as defined in claim 1.
  • FIG. 3 depicts a schematic view of the side of a test device 200 according to one embodiment of the present invention.
  • the test device 200 includes a format 205, a pickup area 210, a transfer area 220, a read area 230, a vent area 240, and a cover 250.
  • the test device 200 is designed to collect a fluid, for example, blood, so the fluid may be tested for the concentration of a particular analyte, such as glucose.
  • a fluid for example, blood
  • analyte such as glucose
  • the fluid described will be blood pricked from a finger and the analyte will be glucose. It is understood that the embodiment may also be used for other fluids and analytes and that these only serve as examples.
  • the pickup area 210 is placed in contact with the wound. Using capillary action, described below, the blood moves into the pickup area 210. The blood flows from the pickup area into the transfer 220 and then into the read area 230. The cover 250 develops the capillary gap in the read area 230 and also retains the blood within the test device, protecting the test unit from contamination.
  • the read area 230 includes a reagent which is designed to react with the glucose to produce a colormetric or electrochemical response.
  • the test unit 100 then measures the colormetric or electrochemical response.
  • the reagent used in the read area 230 depends on the type of analyte desired.
  • the test device 200 can be used in conjunction with a photometric test unit, which measures the colormetric reaction.
  • a photometric test unit measures the colormetric reaction.
  • the reagent used causes a change in color in the read area.
  • the photometric test unit then reads the amount of color change.
  • Photometric testing is described in more detail in commonly-owned U.S. patent No. 5,611,999 entiled "Difffuse Reflectance Readhead". It is also contemplated that other methods of testing the concentration of glucose in blood may be utilized.
  • an electrochemical test unit is employed.
  • the read area 230 includes a pair of electrodes (not shown).
  • electrochemical analysis the change in current across the electrodes caused by the reaction of the glucose and the reagent creates an oxidation current at the electrodes which is directly proportional to the user's blood glucose concentration.
  • the current can be measured by an electrochemical test unit coupled to a pair of terminals (not shown) corresponding to the electrodes.
  • the electrochemical test unit can then communicate to the user the blood concentration.
  • An example of an eletrochemical test system is described in detail by commonly-owned U.S. Patent No. 5,723,284 entitled "Control Solution And Method For Testing The Performance Of An Electrochemical Device For Determing The Concentration Of An Analyte In Bood".
  • the pickup area 210 has a first sidewall 260 and a second sidewall 270, which create a capillary gap 280 having a thickness t 1 .
  • the capillary gap 280 thus, facilitates the capillary action. Proceeding the pickup area 210 is a nib 215.
  • the nib 215 does not have either a floor or a ceiling. Elimination of a floor and a ceiling at the pickup area 210 insures that the pickup area 210 is not closed when the nib 215 is in direct contact with the wound on the finger.
  • the pickup area 210 has a volume v 1 , which is larger than the required volume needed to accurately test the blood.
  • the volume v 1 of the pickup area 210 is designed to ensure that at least a requisite amount of blood is obtained with each test. Creating a large pickup area 210 decreases the likelihood that a user will need to retest due to lack of a sufficient volume of blood.
  • the transfer area 220 is in fluid communication with the pickup area 210 and the read area 230.
  • the transfer area 220 is designed to transfer the blood from the pickup area 210 to the read area 230.
  • a second capillary gap 290 having a thickness of t 2 is created in the transfer area by a first and second sidewall 300, 310.
  • the thickness t 2 of the second capillary gap 290 is less than the thickness of t 1 of the first capillary gap 280.
  • the blood will not flow into an area with a smaller capillary gap until the area with the larger capillary gap is completely filled. In other words, an area with a smaller capillary gap cannot exert enough force to draw blood from an area having a larger capillary gap.
  • the transfer area 220 has a volume v 2 which is less than the volume v 1 of the pickup area 210. Since the volume v 1 of the pickup area 210 is larger than the volume v 2 of the transfer area and the pickup area 210 must be filled prior to the transfer area 220 drawing the blood, the testing device 200 ensures that at least a requisite amount of blood is obtained from the user.
  • the read area 230 is an island surrounded by the vent area 240. As blood moves into the read area 230, the air in the read area 230 escapes into the vent area 240. This ensures that the blood continues to flow into the read area 230 and also aids in the prevention of air pockets forming in the read area 230 during the testing process.
  • the read area 230 comprises a floor 320 and a ceiling 330.
  • the floor 320 is a top side of the cover 250.
  • the ceiling 330 in a portion of the format, illustrated in FIG. 3 .
  • the read area 230 does not include any sidewalls.
  • the inventor has found that air can become trapped along the sidewalls of the read area 230.
  • the presence of air in the read 230 increases the risk of obtaining an inaccurate result.
  • By eliminating the sidewalls air cannot become entrapped in the read area 230, as it all flows out into the vent area 240, and the possibility of erroneous test results is decreased.
  • the floor 320 and ceiling 330 create a capillary gap 340 having a thickness t 3 ( FIG. 6 ) that is less than the thickness t 2 of the capillary gap 290 of the transfer area 220. Therefore, blood will not move into the read area 230 until the transfer area 220 is completely filled.
  • the read area 230 has a volume v 3 which is less than the volume v 2 of the transfer area. Thus, once the transfer area 220 is completely filled, there is enough blood drawn into the testing device 200 to insure a proper reading. Since the read area 230 will not begin to draw the blood from the transfer area 220 until the transfer area 220 is full, a use may be assured that enough blood to provide an accurate reading has been obtained.
  • the capillary gap 340 is maintained at a thickness t 3 because the format 205 (the ceiling 330) is made of a plastic film that retains its shape.
  • the volume v 3 of the read area is from about 70 to about 90 percent of the volume v 1 of the pickup area.
  • the pickup area 210 has a volume of from about 5.0 to about 5.5 microliters and the read area 230 has a volume from about 3.5 to about 4.0 microliters.
  • the volume v 2 of the transfer area 220 may be anywhere between the volume v 1 of the pickup area 210 and the volume v 3 of the read area 230.
  • the thickness t 1 of the first capillary gap 280 is in the range of about 0.635 mm to about 0.762 mm (0.025 to about 0.030 inch).
  • the thickness t 2 of the second capillary gap 290 is in the range of about 0.381 mm to about 0.508 mm (0.015 to about 0.020 inch).
  • the thickness t 2 of the second capillary gap 290 is less than the thickness t 1 of the first capillary gap 280.
  • the thickness t 3 of the third capillary gap 340 is in the range of about 0.203 mm to about 0.030 mm (0.008 to about 0.0012 inch).
  • the thickness t 3 of the third capillary gap 340 must remain less than the thickness t 1 and t 2 of the first and second capillary gaps 280, 290.
  • the operation of the device will now be described.
  • the user moves the pickup area 210 into contact with a drop of blood on the user's finger tip.
  • the pickup area 210 then fills with blood from the user's fingertip.
  • the transfer area 220 begins to fill with the blood.
  • the user may then remove the testing device 200 from the user's fingertip. Since the transfer area 220 does not begin to fill with blood until after the pickup area is filled, and the pickup area a volume v 1 greater than the requisite volume needed for an accurate reading, the user be assured that enough blood has been drawn.
  • the blood then begins to fill the read area 230.
  • the sensor then reads the resulting change and indicates the glucose concentration to the user.
  • the read area 230 includes a capillary gap 820 created by supports 830, a filter 810, and a reagent impregnated paper 840.
  • the filter 830 and reagent impregnated paper 840 are below the capillary gap 820.
  • the blood needs to pass through the filter 810 before the reagent reacts with the blood.
  • the capillary gap 820 above the filter 810 is produced by supports in the test device 200 and is arranged in such a pattern to promote spreading across the top surface of the filter 810.
  • a uniform color change can be created along the read surface of the reagent impregnated paper 840, allowing for an accurate reading by a photometric test unit.
  • the capillary gap distance t 4 is less than the thickness t 2 of the capillary gap 290 of the transfer area 220.
  • the flow of blood acts the same in this embodiment.
